Heathkit IM-2260 Digital Multimeter (DMM): History, Demonstration, Theory
In this video, I talk about the Heathkit IM-2260 digital multimeter (DMM). I cover its history, controls and operation, internal views, how to rig up an AC power supply for it, then I do a demonstration of it in operation in all functions, and finally I do a detailed study of the schematic diagram/circuit theory. 00:00 History 06:19 Internal views 25:12 How to make a clone of the Heathkit AC power supply 29:19 Controls overview 32:48 Demonstration of operation 46:49 Schematic/circuit theory
